Definitions

  • the present invention relates to a harvesting device for a machine for harvesting fruits, berries and the like carried by fruit trees and bushes planted in rows, of the type including a straddling chassis and two sets of shaker members mounted face-to-face on the chassis that co-operate to shake the fruit trees or bushes passing between the two sets to detach the fruits, berries or the like therefrom.
  • a system for driving the shaker members In particular it relates to a system for driving the shaker members.
  • the invention concerns in particular, although not exclusively, grape harvesting machines, and will be described more particularly in connection with this type of harvesting, although a machine including the harvesting device according to the invention can equally be used to harvest other fruits and berries, for example blackcurrants, gooseberries or raspberries, or olives or coffee beans.
  • the principle of harvesting grapes is practically the same in most modern harvesting machines. It is a question of shaking the vine by imparting to it a sinusoidal or pseudo-sinusoidal movement of a certain amplitude and frequency adapted to detach the grapes or the bunches of grapes. This movement is communicated to the whole of the vine by shaker members disposed to operate either on the stocks or the stems of the vines or on the vegetation, i.e. on the fruit-bearing area of the vine, depending on the type and number of shaker members used. The percentage of the bunches of grapes and/or grapes that are detached from the vine depends on the number and the amplitude of the oscillations to which a given bunch of grapes is subjected.
  • the number and the amplitude of the oscillations to which a given bunch of grapes is subjected depend on various parameters for which suitable values can be selected, in particular the amplitude and the frequency of the output of the drive mechanism associated with the shaker members, the length of the active area of said shaker members, their stiffness or flexibility, and the rate at which the machine moves forward, and on other factors that are imposed by the vine itself, in particular how it is trained, its shape and the resistance that it opposes to the movement of the shaker members.
  • the number of shaker members and the height of each of them must be adjustable to match them to the height of the vines to be harvested.
  • two or three pairs of shaker members appropriately distributed over the height of the vine are used, for example, whereas for tall vines five or six pairs of shaker members suitably distributed over the height of the vine are used, for example.
  • the user of the harvesting machine may be obliged to modify the number of shaker members and/or to adjust their height several times a day, before starting to harvest the next lot or the next row of vines. It is therefore desirable for it to be possible to adapt the shaker members to suit the vines to be harvested conveniently and quickly.
  • each shaker assembly includes an oscillating vertical plate which is rigidly connected to the corresponding oscillating vertical shaft and to which the first end of each shaker member, which is in the form of an arcuate rod, is detachably attached.
  • each oscillating vertical plate is provided with a series of pairs of holes, the pairs of holes being spaced vertically and the two holes of each pair being spaced horizontally.
  • each shaker member which is in the form of an arcuate rod, includes two holes having a spacing corresponding to that of a pair of holes in the corresponding oscillating vertical plate and is coupled to the latter by means of two clamps that surround the front end of the rod and which are fixed by two screws or two bolts inserted in the two holes of a selected pair of holes in the oscillating vertical plate.
  • two clamps that surround the front end of the rod and which are fixed by two screws or two bolts inserted in the two holes of a selected pair of holes in the oscillating vertical plate.
  • one of the two clamps to be more precise the one between the front end of the rod and the oscillating vertical plate, is made in the form of a reinforcing member that extends horizontally towards the rear over a part of the length of the rod and which curves outwards.
  • the chassis of the harvesting device includes two vertical legs and the second end (usually the rear end) of each shaker rod of each shaker assembly is connected to the chassis by a link that is articulated by a vertical pin to a yoke that is itself fixed against the inside face of one of the two vertical legs by means of two nut-and-bolt fasteners that pass through a selected pair of holes of a series of pairs of holes provided in said vertical leg.
  • a main object of the invention is therefore to provide a harvesting device of the type defined in the preamble but enabling quick and easy modification of the number of shaker members in use in the machine, without shaker members that are to be taken out of service or put into service having to be completely removed from the machine or fed into its interior.
  • a subsidiary object of the invention is to provide a harvesting device of the type indicated above enabling quick and easy modification of the height of each shaker member.

  • This structure is able to achieve the first object of the invention.

  • the immobilising means can consist of a bolt 72 whose shank passes through an oblong opening 73 formed in the latch 71 and cooperates with a nut 74 recessed into the lateral flange 52 a of the half-shell 39 a to clamp and immobilise the latch 71 against said lateral flange 52 a .
  • a threaded hole can be provided in the lateral flange 52 a , instead of using the nut 74 .
  • the lateral flange 52 a incorporates a protuberance 75 that is in linear contact with the latch 71 , between its active part 71 a and the bolt 72 .
  • the latch 71 turns about the line of contact with the protuberance 75 and operates like a lever, bearing on the edge 51 a of the selected orifice 51 and on the protuberance 75 to press the lateral flange 52 a towards the lateral flange 52 b and to press the latter flange against the part 19 a of the oscillating vertical plate 19 .
  • the two half-shells 39 a and 39 b then clamp the vertical shaft 24 and, at the same time, the mount 39 is coupled by the latch 71 to the oscillating vertical plate 19 , as shown in FIG. 8 A.
  • the sliding movement of the latch 71 is guided, on the one hand, by the shank of the bolt 72 and by the opening 73 , and, on the other hand, by a substantially triangular projection 76 on the latch 71 that can slide in a slot 77 in the protuberance 75 .
  • the rod 22 assumes its natural and substantially rectilinear shape. If the rod 22 must be left in an inactive rest position, its reinforcing member 45 is hooked into one of the hook-shaped supports 69 , as shown in FIG. 8 D.
  • the bolt 72 can then be screwed back into the nut 74 to immobilise the latch 71 in its unlatched position. Note that, in the state shown in FIG. 8D , the half-shells 39 a and 39 b of the mount 39 are held together only by the nut-and-bolt fastener 42 , as a result of which the shaft 24 can turn freely in the mount 39 .
  • FIGS. 9 , 10 A and 10 B show another embodiment of the drive means and the coupling means for coupling the front end of each shaker member to the oscillating vertical shaft of the corresponding shaker assembly.
  • FIGS. 9 , 10 A and 10 B components that are identical to or have the same function as those of the previous embodiments are identified by the same reference numbers and are not described in detail again.
  • the oscillating vertical plate 19 of the embodiments described above is replaced by at least one series of coupling and drive lugs 19 that are rigidly fixed, for example welded, to the oscillating vertical shaft 24 at intervals along it, and that project radially relative to it.
  • each lug 19 of one series is aligned with a lug 19 of the other series and all the lugs 19 of both series are in a plane passing through the axis 20 of the shaft 24 .
  • the number of lugs 19 in each series of lugs is at least equal to the maximum number of shaker members 22 of a shaker assembly, and is preferably much greater than that maximum number to provide a wide variety of choice for the height of the shaker members.
  • Each lug 19 includes an orifice 51 adapted to a receive a bolt 42 a of the nut-and-bolt fastener 42 (see FIG. 10B ) enabling the mount 39 associated with the front end 22 a of a shaker member 22 to be coupled detachably to the lug 19 or to two corresponding lugs 19 corresponding to the required height of the shaker member 22 .
  • the mount 39 for mounting the front end 22 a of each shaker member 22 rotatably on the oscillating vertical shaft 24 here also consists of two half-shells 39 a and 39 b , preferably with an anti-friction pad 43 .
  • the nut-and-bolt fasteners 46 , 48 and 47 , 49 for fixing the front end 22 a of the shaker member and the two flanges 44 and 45 to the half-shell 39 a are also used to fix the two half-shells 39 a and 39 b together.
  • the two half-shells could be fixed together by nut-and-bolt fasteners other than the two fasteners 46 , 48 and 47 , 49 .
  • At least one of the two half-shells 39 a and 39 b of each mount 39 has respective lateral parts 81 a and 81 b through which there is a hole 82 and each of which can be detachably fixed by a respective nut-and-bolt fastener 42 to a pair of lugs 19 on the oscillating vertical shaft 24 to couple the corresponding shaker member 22 to said shaft, as shown in FIG. 10 B.
  • the shaft 24 can oscillate without entraining the drive member 22 , which remains in an inactive position, in which it can be held by a hook-shaped support similar to the supports 69 shown in FIG. 2 .
  • the shaft 24 can entrain the shaker member 22 which is therefore active and can operate on the vines to be harvested.
  • each shaker member 22 can be put into service or taken out of service quickly and easily, simply by fitting or removing two nut-and-bolt fasteners 42 (or a single nut-and-bolt fastener 42 if the shaft 24 has only one series of lugs 19 ), without having to feed the shaker member into the machine or to remove it completely therefrom.
  • the lugs 19 could be in horizontal planes perpendicular to the axis 20 , and the lateral portion or portions 81 a and 81 b could be bent at a right-angle so as also to be in horizontal planes.
  • the bolts 42 a of the nut-and-bolt fasteners 42 would be parallel to the axis 20 .
